I put new ink cartridges from my instant ink subscription in my printer but the E0 code and flashing lights will not clear and I cannot use my printer. How do i get the code to clear?

Hi @Messi2020,

Welcome to the HP Support Community

I understand you are getting an error message E0 on your HP DeskJet 2722 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

For more info, refer to - Blinking Lights and Error Codes

Perform the steps mentioned in this document - HP Printer Does not Print and Error Indicates Faulty Ink Cartridge -  An E0 error indicates an unusable cartridge. This occurs when one or both ink cartridges need attention. 

Reseat both cartridges, clean the ink cartridge contacts, restart the printer, and replace one or both ink cartridges if necessary.
